Abstract: 948,336. Valves. ENGLISH ELECTRIC CO. Ltd. Oct. 20, 1960 [Oct. 20, 1959], No. 35505/59. Heading F2V. A rotary valve comprises a closure member 17 having a spherically surfaced portion 18 for co-operation with a seat 20 and a self-aligning mounting 29, 32 on a cylindrical, tubular element 15 which, in the open position, lies with its axis in alignment with the inlet 13 and outlet 14. The element 15 is guided for rotation by a self-aligning ball bearing 26 and by three rollers 24 which coact with a track 27 on a housing 12 which carries, in bearings 36, an actuating shaft 35 sealed by a bellows 37 and carrying an eccentric 39 which coacts with a circular recess 40 in the element 15. Rotation of the shaft 35 when the valve is open first causes the eccentric 39 to rotate the element 15 until it reaches the position shown in which an abutment 22 engages a stop 21 and one of the rollers 24 lies opposite a recess 28 in the track 27. Continued rotation of the shaft then tilts the element 15 about the bearing 26 until the member 17 engages its seat. A second abutment (not shown) similar to the abutment 22 limits the opening movement of the element 15.

Abstract: 751,760. Control of A.C. motors. BROOKHIRST SWITCHGEAR Ltd., and DAVIES, A. R. Dec. 23, 1954 [Dec. 24, 1953], No. 35852/53. Class 38(3) A dropper switch DS on a loom closes when a weft thread breaks, for example, so firing a tube E of the three-electrode cold cathode type. This causes operation of a high-speed telephone type relay RS to open the circuit of the alternating- current motor which drives the loom and to close a braking contactor for the introduction of direct-current braking. In a modification, the dropper switch is connected in a circuit the voltage of which is insufficient to fire the tube until the voltage across a capacitor is added to the circuit-voltage by the operation of the switch (Fig. 2, not shown). In another arrangement, the switch DS is in the primary circuit of a step-up transformer the secondary winding of which provides a peak voltage for firing the tube when the switch closes (Fig. 3, not shown).

Abstract: 1,049,468. Grinding. UNITED STATES ELECTRICAL TOOL CO. Sept. 2, 1964 [Sept. 10, 1963], No. 35932/64. Heading B3D. A grinding machine has a driving motor with a fixed diameter pulley on its shaft connected by a belt to a variable diameter pulley on the shaft of a grinding wheel and means for moving the grinding wheel shaft away from the motor shaft to increase the speed of the grinding wheel shaft to compensate for wear of the grinding wheel. A tool and hand rest 31 is mounted in fixed position on a grinding machine. A grinding wheel 18 is fixed on a shaft 15 mounted in bearings in a housing 17 having a base-plate 22 movable on ways 23 on the machine bed 11 by a screw 28 operated by a hand wheel 29. A variable diameter pulley 26, having halves 20a, 20b urged together by springs 20d, 20c, is fixed on the shaft 15 and connected by a belt 21 to a fixed diameter pulley 13 on the shaft of a motor 12 mounted on the bed 11. With an unworn grinding wheel, and the base-plate 22 abutting a stop 26, the belt 21 rides at the extreme outer periphery of the pulley 20. As the grinding wheel wears, hand wheel 29 is operated to move the grinding wheel 18 towards the rest 31 so as to maintain the correct spacing; the halves of the pulley 20 separate, permitting the belt 21 to ride closer to the shaft 15, whereby the speed of the latter is increased to maintain the peripheral speed of the grinding wheel constant. In a modification, Fig. 4, the motor 12 is moved in the same direction as, but to a lesser extent than, the grinding wheel. The motor 12 has legs 32 riding in the ways 23 which extend all the way across the bed 11. The motor 12 is moved by a screw 33 coupled at 34 to the screw 28 and having a lower pitch than the screw 28.
